DISK SEEDER.

Specification of Letters Patent.

Patented June 7, 1910.

Application filed June 14, 1909. Serial No. 501,942.

T 0 all whom it may concern:

Be it known that I, CARL J. NELSON, a citizen of the United States, andresident of North Milwaukee, in the county of Milwaukee and State of\Visopnsin, have invented certain new and useful Improvements in DiskSeeders; and I do hereby declare that the following is a full, clear,and exact description thereof.

My invention consists in what is herein particularly set forth withreference to the accompanying drawings and pointed out in claim, itsobject being to insure the making of clean furrows opened by rotatorydisks of grain-drills of the type commonly known as disk-seeders Figurel of the drawings represents a side elevation of a grain-drillfurrow-opening disk in connection with a seed-delivery boot that .isprovided with an attachment, in accordance with my invention, having thedouble function of a disk-scraper and plow; Fig. 2, a rear view of theplow and a fragment of the boot therewith, and Fig. 8, a horizontalsection of the disk and a portion of the aforesaid attachment on theplane indicated by line 33 in Fig. 1, the remainder of said attachmentbeing viewed in plan.

Referring by numerals to the drawings, 4 indicates a fragment of adrag-bar fastened to a forwardly extending arm 5 of a seeddelivery boot6 of a grain-drill, and a rotatory furrow-opening disk 7 is suspended inconnection with said arm, as is common in the art. The boot has thesides thereof beveled at its lower end, and matching the beveledportions of said boot are rearwardly divergent integral plow branches 8of an upwardly curved and pointed blade 9 that constitutes a scraper forone side of the disk 7 The plow-branches of the blade are riveted orotherwise rigidly secured to the lower end of the boot that runs in thediskfurrow said blade being otherwise free, and by means of saidplow-branches astraddle of said boot trash is prevented from fallinginto said furrow that is of approximately V-shape and its sides sopacked, by the bootattachment herein shown and described, that there isno crumbling of earth therein ahead of the boot itself, this keeping oftrash and earth out of furrows ahead of the aforesaid boot being ofimportant advan tage in seeding.

It is to be noted that the attachment aforesaid has no function of aseed-shoe, the seed being delivered directly from the boot back of saidattachment that constitutes a combined disk-scraper and plow.

I claim:

In a disk-seeder the combination of a furrow-opening disk, aseed-delivery boot having the sides thereof beveled at its lower end,and a furrow-protector in the form of a single upwardly curved bladeconstituting a scraper for one side of the disk and provided withintegral rearwardly diver gent plow-branches matching the beveledportions of the boot to which they are fastened, said blade beingotherwise free.

In testimony that I claim the foregoing I have hereunto set my hand atMilwaukee. in the county of Milwaukee and State of Wisconsin in thepresence of two witnesses.

CARL J. NELSON.
